SECTION III - SCHEDULED MAINTENANCE AND OPERATION

WARNING / CAUTION

Before performing any maintenance procedure, make certain solar water and electric supply is OFF and cannot accidentally be turned on.

MAINTENANCE AND OPERATION

The water heater is automatic in its operation. It will maintain a full tank of water at the temperature setting of the thermostat. The water heater should not be turned on without first making sure that the tank is full of water and that all air has been released.

FREEZING

The tank should be fully drained in the event the solar water supply water has been turned off and if there is danger of freezing.

QUARTERLY INSPECTION

1.Monitor thermostat

a.Let water heater completely heat to a designated thermostat setting.

b.After thermostat satisfies (that is, when the thermostat actually clicks off), draw water from heater.

c.Compare water temperature of drawn water to the temperature setting of the thermostat when it satisfies. Normal variation between the two points is approximately + 5°F.

d.If these two readings do not coincide within acceptable tolerances and verification has been made of the accuracy of the temperature-reading gauge, replace the thermostat.

2.Lift test lever on relief valve and let water run through valve for a period of approximately 10 seconds. This will help flush away any sediment that might build up in water passageways.

3.Inspect heating coil flange for leakage as follows:

a.Remove heating coil housing cover.

b.Visually inspect heating coil gasket for evidence of leaks.

c.Rub finger around gasket that is between the heating coil and tank flange for any evidence of moisture. If moisture is present or a water drip is observed, follow procedure outlined in Section V.

4.Check for loose electrical connections. Tighten as necessary.
